Why he might be annoying

The attitude between him and the other members of the Cambridge Five was one of mutual loathing.
He infuriated his Soviet handlers with his lack of punctuality and his inability to work a microfilm camera.
He may have been the first spy to give the Soviets information about the atom bomb project.
He claimed to have stopped providing intelligence to the Soviets when World War II ended, but handler Yuri Modin claimed he continued until his 1951 exposure.
His 1964 confession was covered up and he escaped punishment.
His identity as a spy went unpublicized outside the intelligence community for over a decade.
A month before his death, he married an opera singer less than half his age.
He was described by 'The Independent' as 'a testament to the misconceived idealism among Britain's intelligentsia in the 1930s.'

Why he might not be annoying

He achieved the highest score on the British civil service exam.
Ironically, much of the intelligence he passed to the Soviets during WWII -- namely, German battle plans -- was information the British government was already trying to get into Soviet hands through other channels.
Thanks to Joseph Stalin's paranoia, he refused to believe the information the British were sending him until it was confirmed by Cairncross.
He provided information that the Soviets used to defeat Nazi Germany in the critical Battle of Kursk (1943).
In his later life, he became a translator and expert on French authors, especially Moliere.
